  • Page 5: Intended Use

    Suunto EON Steel 1. Intended use The Suunto EON Steel dive computer is designed for use as an optional diving equipment for recreational diving. Suunto EON Steel is intended for use in various types of scuba diving, for example, air, nitrox, trimix and CCR diving. In scuba diving use Suunto EON Steel dive computer displays important information before, during and after the dive to enable safe decision making.
  • Page 6: Safety

    At the dive site, perform your manual pre-checks on each device before entering the water. Dive Computer Pre-check Ensure that: 1. Suunto EON Steel is in the correct dive mode and the display is working as expected. 2. Altitude setting is correct. 3. Personal setting is correct.
  • Page 7 8. All primary and backup gauges for time, pressure and depth, both digital and mechanical, are showing correct, consistent readings. 9. If Suunto Tank PODs are in use, check that Suunto Tank POD is properly installed and the tank valve is open. Please see the Suunto Tank POD User Guide for detailed information and proper use.
  • Page 8 WARNING: Using a dive planner software such as in Suunto DM5 is not a substitute for proper dive training. Diving with mixed gases has dangers that are not familiar to divers diving with air.
  • Page 9 WARNING: Do not use Suunto USB Cable in areas where flammable gases are present. Doing so may cause an explosion. WARNING: Do not disassemble or remodel Suunto USB Cable in any way. Doing so may cause an electric shock or fire.
  • Page 10: Getting Started

    3. Getting started 3.1. Set up To get the most out of your Suunto EON Steel, use some time to customize features and displays. Make absolutely sure that you know your computer and have it set up as you want before getting into the water.
  • Page 11: Icons

    Suunto EON Steel By default Suunto EON Steel has four main dive modes: Air / Nitrox, Trimix, CCR and Gauge. Press and hold the middle button to enter Main menu and select the appropriate mode for your dive under Dive settings » Mode.
  • Page 12: Product Compatibility

    One or more Tank PODs can be paired with the dive computer for multi-gas diving. This dive computer can also be paired with the Suunto app over Bluetooth. With the app you can transfer dive logs to Suunto app.
  • Page 13: Features

    4. Features 4.1. Alarms, warnings, and notifications Suunto EON Steel has color-coded alarms, warnings and notifications. They are shown prominently on the display with an audible alarm (if tones are on). Alarms are always red. Warnings may be red or yellow. Notifications are always yellow.
  • Page 14 Suunto EON Steel Warning Explanation Dive time Dive time exceeds your dive time alarm limit Diluent high pO₂ Diluent partial pressure of oxygen exceeds safe level (>1.6); no immediate danger unless diluent is used, e.g. diluent flush Diluent low pO₂...

    The advantage of Suunto Fused™ RGBM 2 is additional safety through its ability to adapt to a wide variety of situations. For recreational divers it may offer slightly longer no- deco times, depending on the chosen personal setting.
  • Page 21: Diver Safety

    4.11. Decompression dives When on a decompression (deco) dive you exceed the no-decompression limit, Suunto EON Steel provides the decompression information required for ascent. Ascent information is always presented with two values: Ceiling: depth that you should not go above •...
  • Page 22 Suunto EON Steel WARNING: NEVER ASCEND ABOVE THE CEILING! You must not ascend above the ceiling during your decompression. In order to avoid doing so by accident, you should stay somewhat below the ceiling. On a decompression dive, there could be three kinds of stops: Safety stop: this is a recommended three-minute stop for every dive over 10 meters (32.8...
  • Page 23 Suunto EON Steel If you ignore the alarm and stay above the safe margin for three minutes, Suunto EON Steel locks the algorithm calculation, and decompression information will not be available anymore on the dive. See 4.2. Algorithm lock. Decompression display examples Below is a typical decompression dive view showing ascent time and the first required deepstop at 20.3 meters:...
  • Page 24: Last Stop Depth

    NOTE: If the ceiling is broken for more than 3 minutes, the decompression algorithm gets locked. Below is an example of what Suunto EON Steel displays during a deepstop: With decompression stops, in the continuous ascent mode the ceiling is constantly decreasing while you are near the ceiling depth, providing continuous decompression with optimum ascent time.
  • Page 25 It all comes down to proper control of the expanding gas during an ascent. This is why all Suunto RGBMs use a maximum ascent rate at 10m/minute, which has proven over the years to be an effective protective measure.

    For display brightness adjustment, see 5.2. How to change display brightness. 4.15. Dive history Dive history is a summary of all the dives done with your Suunto EON Steel. The history is divided according to the dive type used for the dive. Each dive type summary includes the number of dives, cumulative dive hours and maximum depth.

  • Page 32: Gas Mixtures

    NOTE: When you have analyzed your gas, you should round the result down when entering it for Suunto EON Steel. For example, if the analyzed gas is 31.8% oxygen, then define the gas as 31%. This makes the decompression calculations safer.
  • Page 33: Gas Time

    Gas time information is not visible by default. After customization in DM5, the information will be visible in the lower right-hand corner of the screen. If you have not paired a Suunto Tank POD, the gas time field shows n/a. If you have paired a POD but there is no data being received, the field shows –.
  • Page 34: Logbook

    NOTE: If you surface and then dive again within five minutes, Suunto EON Steel counts this as one dive. 4.25. Multi-gas diving Suunto EON Steel allows gas changes during a dive between the gases defined in the Gases menu. When ascending, you are always notified to change gases when a better gas is available.
  • Page 35: Modifying Gases During A Dive

    In another case, if for some reason a diver runs out of gas and needs to use a gas mixture from a dive buddy, it is possible to adapt Suunto EON Steel to the situation by adding the new gas mixture to the list. Suunto EON Steel re-calculates decompression and shows the correct information for the diver.

    2. Geometric mean of the partial pressure change of N2 and partial pressure change of He is bigger than 0.35 bar. If these limits are exceeded with a gas switch, Suunto EON Steel indicates the risk of ICD as shown below: In this example, the available gas mixtures for a deep Trimix dive are: Trimix 15/55, MOD 76.7m (pO...
  • Page 37 (DCS). The default setting for the Suunto Fused™ RGBM and Fused™ RGBM 2 is to use a compromise (0 setting) between conservative and aggressive. With the personal setting, you can select gradually more conservative or more aggressive calculations.
